What is Combustion?

The chemical process in which a substance reacts with oxygen to give off heat is called combustion.

Examples are ethane, wood, propane.

There are three types of Combustion: 

1. Rapid combustion

Rapid combustion is a form of combustion where large amounts of heat and light energy are released rapidly.

 

2. Spontaneous combustion

Spontaneous combustion is a type of combustion that occurs by self-heating (raise in temperature during exothermic reactions), followed by thermal runaway (self-heating accelerating temperature) and resulting in the ignition.

 

3. Explosions

An explosion is a sudden increase in volume and temperature resulting in the release of energy and gases. For example Explosion due to bomb blast and underwater nuclear test.
